Summary: The study established the influence of the crystalline phase and agglomeration degree of TiO2 nanoparticles on photocatalytic hydroxyl radical formation and bacterial inactivation in TiO2/SiO2 composite coatings. A relationship between hydroxyl radicals' formation and charge carrier transfer mechanism between defect levels in SiO2 and TiO2 embedded nanoparticles was established through a simple spectroscopic method. This correlation complements the lack of mechanisms behind the photocatalytic activity in TiO2/SiO2 composites.

Summary: A polypyrrole-modified Fe3O4/SiO2/TiO2 composite material was successfully synthesized on the FST surface by in situ polymerization of pyrrole. The structural, morphological and magnetic response were characterized, and the catalytic activity of the material was evaluated. The results showed that FST/PPy exhibited excellent photocatalytic activity and the degradation rate was significantly improved under visible light. Furthermore, the photocatalyst could be easily recycled using a magnet.

Summary: The study evaluated the durability of ZnO and TiO2 nanoparticles-modified cotton terry textiles in terms of photocatalytic and antimicrobial activities. Results showed that the efficiency of self-cleaning properties and antimicrobial activity depended on UVA/B radiation intensity, with a significant increase in photocatalysis effectiveness at higher radiation intensities. A biocidal effect against all tested microorganisms was observed at a UVA/B radiation intensity of 1400 mu W/cm(2). Additionally, the antimicrobial activity of washed materials could be increased by irradiation with a light bulb.

Summary: A series of mixed-phases TiO2 were fabricated using a mild hydrothermal process, resulting in nanocrystals with different combinations of anatase, rutile, and brookite phases. While the triphase TiO2 showed the longest optical edge in UV-vis absorption spectroscopy, the diphase TiO2 exhibited higher degradation ratio of levofloxacin. This study provides insights into regulating the phase ratio of TiO2 for environmental remediation applications.

Summary: The results of studying the recovery of nitric acid and NaOH + KOH alkalis' mixture from concentrated solutions using filter-press-type electrodialyzers with anion-exchange, cation-exchange, and bipolar membranes are presented. It was found that the preliminary purification of the solutions from calcium and boron compounds is necessary to obtain crystalline boric acid and gypsum. The study demonstrates the possibility of obtaining purified acids and alkalis suitable for reuse from concentrated salt solutions. Electrodialysis with anion- and cation-exchange membranes is the most effective method, while electrodialysis with bipolar membranes leads to noticeable contamination of the solutions with salts.
